To make a space on a desk to be large for work except computer operation, and to make startable the computer operation at any time by installing a drawer beneath a top plate, and accommodating and fixing a thin display device therein.

The top face of a transparent glass top plate 2 inserted by notching a part of this side of a top plate 1 is fitted so that it becomes a plane similar to the top face of the top plate 1. A drawer 3 is fitted so that it can be drawn out or pushed in below the top plate 1 by guide rails. A liquid crystal monitor 11 being the display device of a computer is accommodated and fitted in the drawer 3. The liquid crystal monitor 11 is drawn to this side and it can easily be viewed in a state where the drawer 3 is drawn out. Since a keyboard 12 is accommodated below the top plate 1 and it is hidden in the state where the drawer 3 is pushed in, the keyboard 12 is not projected when the computer is not operated.
